To all whom it may concern Be it known thatwe, JOHN E. If AEERLE andJULIUS B. B. STRYKER, citizens of the United States, the former aresident of South Bend, county of St. Joseph, State of Indiana, andthe'latter a. resident of Lens: dale, county of Montgomery, State ofPenn sylvania, have invented certain new and useful Improvements inGlue-Spreading Machines, of which the following is a specification. v

Our invention relates to improvements in glue spreading machines andthelike, and is especially directed to improvements in a machine such asshown in applicatiom'Serial No. 614,038, filed March 13th, 1911.

One object of the invention is to provide a more eificient and simplemeans for adjust ing thesp'ace between the glue rolls. I A furtherobject is to provide improved .means for scraping the ends of the gluerolls and for closing the ends of the glue troughs.

Further objects, featuresand advantages will more clearly appear fromthe-detailed description given below, taken in connection with theaccompanying drawings whichform a part of this specification. j

In the drawings, Figure l-is a transverse section through amachineembodying the improvements in one form. Fig. 2 is a frontelevation of, such a machine, certain parts being broken away in orderto more clearly illustrate the same. Fig. 3 .is a detailed transversesection taken on the line 33 of Fig. 2. Fig. .4 a perspective'of one ofthe scrapers applied to the end of the glueroll. Referring to thedrawings, 1 represents a suitable framein which is journaled a lowerglueroll2..

Situated belowvthe glue roll 2, and into which the glue roll 2, dips isa glue apply ing trough 3 provided with a perpendicular wall 4 on oneside thereof. The glue trough 3 as so far described is rigid with the,

frame 1. I

Pivoted by means of bearings 5 is a member 6 carrying a scraper 7, thescraper 7 having integral therewith a' wall 8 which arn, PENNSYLVANIA,assienoas 'ro mamas GLUE coivrramz, a oonronarron ernn-sranamtieiii-Asmara.

forms .an extension of the wall 4, for the glue trough 3. The scraper 7may be ad justed with respect to the surface of the glue roll 2hy meansof set screws 9 passing through thescraper, and coiiperating with bosses10 rigid with the main frame.

For holding the scraper in placetoward the glue roll 2, arms 11 areprovided, one at either end, and pivoted or journaled at 12 in thehearings of the glue roll 2. These arms 11 are arranged to engage forkedmemhers 13, rigid with the rear wall8, and ex tending from the endsthereof, and on the 'outer end of the arms 11 are screwed knurled handnuts 14.. By screwing up the hand nuts 14 the scraper 'Z'may be forcedinto place, and disposition finally occupied by the scraper 7 willdependupon the adjustment-of the screws 9.

When it is desired'to clean out the glue trough 3 the hand nuts14 areslightly unforks 13, when thescraper 7 with its back -wall'8- may beoscillated backwardly about thepivoting means 5, so that ready accessmaybe had into the fr'ont portion of the trough 3. It will therefore beseen that a joint is formed at 15, in the back wall 4, 8,

of the glue trough, and that in the ordinary operation of the machineglue would be' apt to work out through this joint. In order to preventthis there is provided a metallic member 16, rigidly secured to the backporscrewed, whereupon the arms 11 may bethrown outwardly to-one side outof the tion 8, by means of screws 17, and bent at the trough 3 by meansof screws 20, are

' scrapers 21. The scrapers 21 are bent substantially at right angles at22, to form scraper faces23 and faces 24, in which are slots 25, throughwhich the screws 20 pass.

The edge 26 of the face 21 engages the end close to the end of the roll2 and near its periphery, as clearly shown in Figs. 1 a iid 3.

Secured to the ends of the scraper 7 by screws 28, are end plates 29which are adapted to close the end of the glue trough 3 at this point.The plates 29 have an edge 30, which when the scraper 7 is forced intooperative position, practically engages the face of the upturnedextension 27, while the edge 31 of the plate 29 lies at or below the topof the end of the glue trough 3.

By the partsv above described, the glue trough on the side of the glueroll is thoroughly closed up so as to prevent any glue from working out,and yet the parts are simple and easy of construction, and easily putinto place and adjusted.

At 32 is shown a pipe lying-in the glue trough 3, and adapted to be fedwith steam from the outside by means of pipes 33 and- 34. The steamprovides heat if desired for the purpose of warming the glue in the gluetrough 3.

Pivotally mounted as at 35 are two lever arms 36 and 37. Journaled inthe inner ends 39 of these lever arms is an-upper roll 38. The innerends of these lever arms carry also a glue trough 40 provided with ends41, to which is pivotally .mounted by means of shaft 42 a front wall 43,carrying a scraper 44 for scraping the upper glue roll 38. The frontwall 43 is hollow, as at 44, and steam is admitted thereto by pipes 45for the purpose of supplying heat to heat the glue in the trough 40.

46 represents rods pivoted to the wall 43 at 47, and the rods 46 areadapted to engage forked members at 48, and have screw threaded on theirouter ends knurled hand nuts 49. The wall 43 has screw threaded thereinadjusting screws 50 which coiiperate with bosses 51 to adjust thedistance between the scraping edge of scraper'44 and the face of theroll 38.

Tie rods 52 and 53 serve to rigidly hold the ends 41 in position.Rigidly secured to the tie rod 51 is a plate 54 extending sulostantiallythe whole length'of the roll,'as shown" in Figs. 1 and 2, which plateacts as a guard to the hands of the operator to prevent them from comingin touch with the roll 38, and being dragged between the two glue rolls.A

The outer ends 55 of the lever arms 36 are provided with cup shapeddepressions, as at 56, which are engaged by semi-spherical heads 57,secured upon. connecting rods 58. Each of the two connecting rods 58passes through an opening in an arm 59, and is secured thereto by meansof nut 60. The

arms-59 are rigidly secured to a rock shaft 61,*suitably journaled inthe frame of the machine. Also rigidly secured to the rock. shaft/61 isa third arm 62, which extends upwardly therefrdm, as clearly shown inFigs. 1 and 2. Screw threaded in the frame ofthe machine is screw 63having rigid therewith at its outer end a hand wheel 64. The inner endof the screw 63e11- gages a head 65 integral with the end of the arm 62.It will therefore be seen that by turning the hand wheel 64 the shaft 61will be oscillated, thereby rocking the arms 59 and communicatingmovement through the rods 58 to both of the lever arms 36 and 37simultaneously, so that both ends of the roll 38 are movedsimultaneously and to the same extent. Adjustment of one end of the roll38 without the other may be had by means of nuts 66 upon the upper endsof the connecting rods 58. It will therefore be seen that especiallysimple and efiicient means are provided for moving the upper roll 38 andadjusting it with respect to the lower roll, in which only one handwheel is Codperating with the scale 67 is a pointer 68 rigidly securedto the bearing of the lower roll, as at 69. It will thus be seen thatthe scale 67 and the pointer 68 coiiperate to indicate the distancebetween the two glue applying rolls 2 and 38, whereby they may bereadily and quickly adjusted by the operator to accommodate theparticular thickness of material to be operated upon.

Although we have described our improvements in great detail and withrespect to one particular embodiment thereof, nevertheless we do notdesire to be limited to such details except as clearly specified in theappended claims, since many changes and modifications may well be madewithout departing from the spirit and scope of our invention in itsbroadest aspects.
